The great waterfalls are in the gorge in a distance of 4km from the village Agios Ioannis of Parnonas. The big waterfall has height 70m and the small one 45m. The climbing clubs organise canyoing and rapel there. These waterfalls are considered to be of the most beautiful, but unknown miracles of nature of Parnonas. The rocks around the waterfalls are brown and the water falls harshly on them. The are smells origan, sage as the small plane-trees make a picturesque scenery. In summer there is a pond for swimming.
